Patent JP-S62213924-A (JP)
Title: Wire electrode for high-precision machining
Inventor: NAO HITOSHI
IPC: B23H7/08
Filed: 1986-03-14
Abstract: PURPOSE:To make high-precision and high-speed machining performable, by setting the thickness of a zinc or zinc alloy covered layer to a range of 0.5-4mum, and forming an interface between a core and the covered layer into smoothness enough. CONSTITUTION:Thickness of a zinc or zinc alloy covered layer is made so as to be set to a range of 0.5-4mum. This is because if thickness is less than 0.5mum, consumption of zinc is little but improvement in a machining speed is almost nothing, and if it is less than 4mum the other way, the consumption of zinc unduly grows larger and, what is worse, machining accuracy is lowered. Likewise, if irregular surfaces exist on an interface between a core and the covered layer, irregular surfaces of this core are exposed due to consumption of the zinc whereby machining is not uniformized, thus surface roughness turns worse. Therefore, electroplating, not a mechanical process, is carried out so that it is smoothable in this way. With this constitution, performance for high- precision and high-speed machining is improvable.

IPC: G11B20/12
Filed: 1989-03-07
Abstract: PURPOSE:To effectively correct a sound signal only by a sound signal included in the same sequence and to effectively execute various sound signal processing in the vicinity of an edition point by separating data obtained before and after the edition point to prevent sound signals included in respectively different sound sequences from being mixed with each other. CONSTITUTION:When a sound signal from the 1st 2-stage parallel latch circuit 7 is selected by the 1st switch 12, an error signal from the 1st 2-stage 1-bit latch circuit 9 is selected by the 2nd switch 13. When a sound signal from the 3rd 2-stage parallel latch circuit 15 is selected by the 5th switch 17, the sound signal is reproduced by interpolation based upon sound signals outputted before and after the sound signal concerned if an error is included in the sound signal. If the sound signals outputted before and after the sound signal concerned have errors, correcting processing is executed so that the sound signals having the errors are substituted. Consequently, the correcting processing before and after an edition point can be effectively executed.

Filed: 1990-03-09
Abstract: PURPOSE:To prevent deviation of focus when a desired figure is exposed to an electron beam, and enable accurate drawing, by installing a table having a constant radius of curvature and a film having constant thickness and width. CONSTITUTION:An electron beam 1 corrected by a correction coefficient operating circuit 13 and the like is projected on a film 6A on a table 17 having a constant radius of curvature, so as to keep the beam work distance between the center of a main deflector 5 and the film 6A constant (constant distance). The film 6A is closely put on the table 17, and has constant thickness and width. Hence drawing is performed by drawing a pattern on the film 6A by using the electron beam 1, so that height correction and the like for each substrate in the conventional art are unnecessitated. That is, by installing the film 6A and the table 17, the beam work distance is not changed, whatever positions of the film 6A may be irradiated with the beam 1. Thereby beam drawing distortion is not generated, and highly precise drawing is enabled.
